Mass Transfer If f = moles of vapour present per mole of feed, then the slope of feed line is - f/(1 - f) (1 - f)/f - (f - 1)/f - 1/f - f/(1 - f) (1 - f)/f - (f - 1)/f - 1/f ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer Acetone is to be removed from air in an isothermal dilute absorber using pure water as solvent. The incoming air contains 5 mole% of acetone (yin = 0.05). The design equation to be used for obtaining the number of trays (N) of the absorber is, N+2 = 6 log (yin/yout).For 98% recovery of acetone, the number of trays required is/are 1 8 9 10 1 8 9 10 ANSWER DOWNLOAD EXAMIANS APP

Mass Transfer Experiments were conducted to determine the flux of a species A in a stagnant medium across a gas-liquid interface. The overall mass transfer co-efficient based on the liquid side for dilute systems for the above was estimated to be 4 x 10⁻³ kg mole/m².s. The equilibrium data for the system is given as y = 2x. The flux across the interface (in kg mole/m² .s) for bulk concentrations of A in gas phase and liquid phase as y = 0.4 and x = 0.01 respectively is 5.6 x 10⁻³ 5.6 x 10⁻⁴ 8.5 x 10⁻³ 8.5 x 10⁻⁴ 5.6 x 10⁻³ 5.6 x 10⁻⁴ 8.5 x 10⁻³ 8.5 x 10⁻⁴ ANSWER DOWNLOAD EXAMIANS APP
